Nice article.
I am not an expert in quantum, but it was really nice to read about muons and chances of the presence of new unknown particles due to difference in theoretical and experimental values.
Actually this is how science advances. From theories we get idea of new experiments and from experiments we get new theories. Both are complementary, and that's why this is science. :D
The level of calculation is such that even when you know how it works, it is tough to go to such a level of precision. Only a few people around the world can.
